LOUIS S. ORITTENDEN, OF HORNELLSVILLE, NEW YORK, ASSIGNOR OF ONE- HALFTO CHARLES W. STEVENS, OF SAME PLACE.

WOODWORKlNG-TOOL.

SPECIFICATION forming part of Letters Patent No. 508,412, dated November14, 1893.

Application filed March 16, 1893.

To all whom it may concern:

Be it known that I, LOUIS S. ORITTENDEN, a citizen of the United States,residing at Hornellsville, in the county of Steuben, State of New York,haveinvented certain new and useful Improvements in Woodworking-Tools,of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to certain new and useful improvements in woodworking tools of that class which are designed for boring,

vide a simple and cheap tool embodying an anger and a reamer whereby thehole may be bored and then byacont-inued use of the same tool the saidhole may be reamed out as may be desired. I mount upon the shank of theauger a tapered block or casting which may be adjustable thereon andwhich is provided with a plurality of rasps which are preferablyadjustably supported thereon. The block or casting may assume anydesired shape in cross section and is formed with a cavity or chamberthrough which the shank of the auger passes, this being provided soas toavoid the necessity of shaping more than the hearing at each end thereoffor the shank. The rasps may extend partially or wholly the length ofthe block or casting and may be held thereto in any suitable manner. Theblock or casting with its rasps may be removed from the shank whendesired.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification and in. which-' Figure 1 is a side View of a portion of myimproved combined auger and reamer. Fig. 2 is alongitudinal sectionthrough the reamer portion with the shank in place therein. Fig. 3 is across section through the reamer portion. Fig. 4 is a modification.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings t the shank.

Serial No. 466,329. (No model.)

by. letter, A designates an anger which may of, as seen in Figs. 2 and3, and at opposite ends of this chamber or cavity it is bored forthepassage of the shank of the auger. The formation of this chamberlightens the casting, avoids the necessity of truing more than the endbearings for the shank, and the chamber may be used as a lubricantreceptacle in which may be placed a little lubricant to prevent rustingor sticking of the casting upon This block or casting is secured to theshank preferably by means of screws 0 which are designed to be screwedthrough the casting as seen in Fig. 3 and bear upon the shank, thescrews being formed with polygonal sockets c for the reception of asuitable implement for turning the same, the screw holes being formed ina longitudinally hollowed portion 19' of the casting as seen in Fig. 3so as to permit of the heads of the screws being sunk below theperiphery of the casting.

Around the periphery of the block or casting I arrange a plurality oflongitudinallydisposed rasps D which are arranged in longitudinalgrooves 01 in the casting as seen best in Fig. 3, the said rasps beingheld therein as by the screws E taking into holes in the casting asseen'in Figs. 2 and 3. These rasps may extendthe entire length of thecasting as shown in Figs. 1 and 2 or they may be of less length than thecasting as indicated in Fig. 4, and when thus of less length they may beadjustable lengthwise on the casting by forming the rasp with alongitudinal slot as shown at e in said Fig. at, the screw passingthrough said slot as indicated in said view.

In operation the hole is bored by the auger and then the continuedrevolution thereof brings the reamer into action. The reamer may bemoved along on the shank of the auger any required distance to permit ofthe boring of the hole of the required depth. Any suitable form of raspmay be employed.

Modifications in detail may be resorted to Without departing from thespirit of the invention or sacrificing any of its advantages.

WVhat I claim as new is- 1. The combination with an anger, of a reameradj ustably mounted on the shank thereof and provided with independentrasps, extending lengthwise thereof, as set forth.

2. The combination with an anger, of a reamer adjustably and removablymounted on the shank thereof and provided with adj ustable rasps, as setforth.

3. The combination with an anger and its shank, of a tapered casting adjustably mounted on said shank and having an interior chamher andexterior rasps, as set forth.

4. The combination with the tapered casting having interior longitudinalchamber and shaft bearings at opposite ends thereof, of rasps seateddetachably in longitudinal channels on the casting, substantially asspecified.

5. The tapered casting having longitudinal channels and a longitudinalbore enlarged near its center, and a longitudinal exterior groove,combined with rasps seated in the channels, and securing means locatedin the said groove, as and for the purpose specified.

In testimony whereof I alfix my signature in presence of two witnesses.
